Summary

Red Hat Security Advisory: OpenShift Container Platform 4.1.24 runc security update

Severity

Moderate

Notes

Topic: An update for runc is now available for Red Hat OpenShift Container Platform 4.1. Red Hat Product Security has rated this update as having a security impact of Moderate. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section.

Details: Red Hat OpenShift Container Platform is Red Hat's cloud computing Kubernetes application platform solution designed for on-premise or private cloud deployments. This advisory contains the runC container image for Red Hat OpenShift Container Platform 4.1.24. The runC tool is a lightweight, portable implementation of the Open Container Format (OCF) that provides a container runtime. Security Fix(es): * runc: AppArmor/SELinux bypass with malicious image that specifies a volume at the /proc directory (CVE-2019-16884) For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section.

CVE-2019-16884

runc through 1.0.0-rc8, as used in Docker through 19.03.2-ce and other products, allows AppArmor restriction bypass because libcontainer/rootfs_linux.go incorrectly checks mount targets, and thus a malicious Docker image can mount over a /proc directory.
